SCA: security update for io.opentelemetry.javaagent:opentelemetry-javaagent (GHSA-xw7x-h9fj-p2c7)

critical Tenable Self-Hosted Container Security Plugin ID 439231

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - OpenTelemetry Java Instrumentation provides OpenTelemetry auto-instrumentation and instrumentation
 libraries for Java. In versions prior to 2.26.1, the RMI instrumentation registered a custom endpoint that
 deserialized incoming data without applying serialization filters. On JDK version 16 and earlier, an
 attacker with network access to a JMX or RMI port on an instrumented JVM could exploit this to potentially
 achieve remote code execution. All three of the following conditions must be true to exploit this
 vulnerability: First, OpenTelemetry Java instrumentation is attached as a Java agent (`-javaagent`) on
 Java 16 or earlier. Second, JMX/RMI port has been explicitly configured via
 `-Dcom.sun.management.jmxremote.port` and is network-reachable. Third, gadget-chain-compatible library is
 present on the classpath. This results in arbitrary remote code execution with the privileges of the user
 running the instrumented JVM. For JDK >= 17, no action is required, but upgrading is strongly encouraged.
 For JDK < 17, upgrade to version 2.26.1 or later. As a workaround, set the system property
 `-Dotel.instrumentation.rmi.enabled=false` to disable the RMI integration. (CVE-2026-33701)

Solution

Update the io.opentelemetry.javaagent:opentelemetry-javaagent library and its related packages to version 2.26.1 or later.
